Portable Spot Coolers: Refrigerant DH-A Units
Refrigerant, not evaporative: the spot coolers on this page use a compressor with refrigerant (R22/R410A). They are portable air conditioners for a single spot, not evaporative coolers, and they are described as such throughout this site.
A spot cooler cools a spot. That sentence is the whole buying logic for this family. Where a duct evaporative cooler ventilates and cools a zone with fresh air, a DH-A spot cooler uses a compressor and refrigerant to cool the air around one workstation, one machine, or one small room — and it does so without adding humidity to the rest of the building.
The four sizes
| Model | Cooling | Airflow | Input power | Current | Water tank | Size (mm) | Weight |
|---|---|---|---|---|---|---|---|
| DH-A-27B | 2700 W (9207 BTU) | 400 m3/h | 1050 W | 4.8 A | 6 L | 415 x 465 x 960 | 56 kg |
| DH-A-35B | 3500 W (11935 BTU) | 550 m3/h | 1200 W | 5.5 A | 6 L | 460 x 465 x 1065 | 65 kg |
| DH-A-45B | 4500 W (15345 BTU) | 800 m3/h | 1800 W | 11 A | 11.5 L | 510 x 500 x 1050 | 56 kg |
| DH-A-65B | 6500 W (22165 BTU) | 1200 m3/h | 2500 W | 12.5 A | 11.5 L | 585 x 545 x 1220 | 103 kg |
All four run on 220 volts at 50 hertz, work in ambient temperatures from 16 to 45 degrees Celsius, roll on 360-degree casters, plug in and run, and carry a washable filter. Single, double and triple-duct variants share this family: the duct count changes how the cooled air is delivered and where the warm air goes, not the cooling capacity. Say which variant you need in your inquiry, because a single-duct unit and a triple-duct unit are not interchangeable on site.
Spot cooler or evaporative cooler: the honest split
- Choose a spot cooler when the job is one spot: a workstation, a machine operator, a server corner, a small sealed room. The unit cools that spot and leaves the rest of the building alone.
- Choose evaporative when the job is a zone or a hall: fresh air wanted, doors open, humidity not a problem. The duct family on this site covers that job.
- Choose a spot cooler when humidity control matters: evaporative cooling adds moisture to the air it delivers, which is the wrong direction for humidity-sensitive work or sealed rooms.
- Do not choose on the word portable alone. Both families are portable. What differs is the technology inside and the size of the job outside.
Spot cooler models
Before ordering, confirm: the exact model and voltage for your site, the airflow and size you need, MOQ, lead time, and warranty. This page lists only what the source material verifies; anything not listed here is a question to ask, not a specification to assume.
Request a mobile cooling layout
Send your space size, heat source, and voltage, and ask for a layout using the equipment families on this page. Before payment, confirm MOQ, lead time, voltage, and warranty for your order.
